When flushing objects larger than the CPU cache it is preferrable to use a single wbinvd() rather than overlapping clflush(). At runtime, we avoid wbinvd() due to its system-wide latencies, but during singlethreaded suspend, no one will observe the imposed latency and we can opt for the faster wbinvd to clear all objects in a single hit.
